Key tropical crops at risk from pollinator loss due to climate change and land use
Insect pollinator biodiversity is changing rapidly, with potential consequences for the provision of crop pollination. However, the role of land use–climate interactions in pollinator biodiversity changes, as well as consequent economic effects via changes in crop pollination, remains poorly understood. We present a global assessment of the interactive effects of climate change and land use on pollinator abundance and richness and predictions of the risk to crop pollination from the inferred changes.
American Farmland Trust applauds introduction of bipartisan bill to advance agrivoltaics
Agrivoltaics refers to the practices of integrating solar energy generation and farming on the same piece of land, which could potentially reduce displacement of agricultural production from farmland as a result of solar development. The concept has been gaining attention in land-constrained countries like Japan and Germany as well as in states like Massachusetts and New Jersey.
“If included in the Farm Bill,” Fink said, “the Agrivoltaics Research and Demonstration Act would secure USDA’s role in advancing this innovation alongside the Department of Energy, AFT, and other partners across the country. Together, we are seeking ways to reduce displacement of farming from productive land as a result of solar energy development.”
Carbon farming
Agriculture is part of the climate solution. Grasslands are one of the largest carbon sinks on the planet, capable of pulling enormous quantities of CO2 from the atmosphere and storing it in the soil.
Carbon farming is the process of farming and ranching to maximize the land’s ability to lock up CO2 and other greenhouse gases, making the land more resilient to the effects of a changing climate.
Marin Agricultural Land Trust (MALT) partners with MALT farmers and ranchers to implement carbon farming practices, benefiting farmers, their land, and the climate…
Land trusts ink deal to conserve 20 acres along Mill River in Williamsburg
Mark Wamsely, [Kestrel Land Trust’s] conservation director, highlighted the conservation as a way to combat climate change. The [press] release also notes the state’s 2022 Climate Change Assessment, which states that risk of flooding and erosion in the hilltowns is likely over the coming century.
“It’s important that we address climate change in a thoughtful way and don’t accidentally harm the very natural resources that are under threat,” said Wamsley, adding that, “Conserving forests is one way the Hilltowns can make a critical contribution to combating climate change.”
Climate change website pages
Land trusts often wonder how they can increase their efforts to connect with people around climate change, meet them where they are, and inspire local, regional, and national action.
Many land trusts start with nature-based climate solutions as a way to connect. However, it’s important for people to also understand what they can do as individuals based upon their interests and capacity, in addition to what the land trust is doing.
If you are interested in enhancing climate messaging or raising the profile of your local land trust, you might find the Coastal Prairie Conservancy’s climate pages of interest.
Mississippi Valley Conservancy planting trees to help combat climate change
Carol Abrahamzon, Executive Director of the Mississippi Valley Conservancy, met with the local TV station to talk briefly about a restoration project they are working on.
“Abrahamzon says these trees are essential to providing a healthy habitat to the Coulee Region. The trees to be planted at the Conservancy’s Trempealeau Lakes nature preserve include swamp white oak, silver maple, and river birch.
Abrahamzon says that the selected tree species are native to the Driftless Area and will adapt well to this site and require little care after they become established. All of these benefits strengthen the land’s resilience to a changing climate…”
New research shows global climate benefits of protecting nature, but it’s not a silver bullet
Since 2000, the researchers reported, protected forests worldwide have stored 9.65 billion metric tons more carbon in their trunks, branches, and stems than ecologically similar unprotected areas. That is equal to about a year’s worth of annual carbon dioxide emissions from human activities. But that doesn’t mean that nature is a silver bullet that will stop climate change, said lead author Laura Duncanson, an assistant professor and remote sensing scientist at the University of Maryland who studies global carbon stocks.
Trees are moving north from global warming. Look up how your city [region] could change.
As the climate warms, horticulturalists are trying out species adapted to more southern climates. Michael Hagen, curator of the native plant and rock gardens at the New York Botanical Garden, told me recently that his colleagues are planting southern live oaks, known for the Spanish moss that drapes, ghostlike, from their limbs.
Live oaks can grow as far north as Zone 7, according to data provided by the Davey Tree Expert Company. By century’s end, they could grow in Chicago and up into Michigan, while south Florida could become too hot for them.
Assessing the climate change mitigation potential from food waste composting
Food waste is a dominant organic constituent of landfills, and a large global source of greenhouse gases. Composting food waste presents a potential opportunity for emissions reduction, but data on whole pile, commercial-scale emissions and the associated biogeochemical drivers are lacking. We used a non-invasive micrometeorological mass balance approach optimized for three-dimensional commercial-scale windrow compost piles to measure methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2) emissions continuously during food waste composting. Greenhouse gas flux measurements were complemented with continuous oxygen (O2) and temperature sensors and intensive sampling for biogeochemical processes.
How much food waste is there in the United States?
Each year, 119 billion pounds of food is wasted in the United States. That equates to 130 billion meals and more than $408 billion in food thrown away each year. Shockingly, nearly 40% of all food in America is wasted.
Food goes to waste at every stage of food production and distribution – from farmers to packers and shippers, from manufacturers to retailers to our homes. Food waste in our homes makes up about 39% of all food waste – about 42 billion pounds of food waste. While commercial food waste makes up about 61% of all food waste or 66 billion pounds of food waste. Feeding America focuses on reducing food waste on farms and in food service, manufacturing, and retail.
